DS14C88
QUAD CMOS Line Driver
General Description
The DS14C88, pin-for-pin compatible to the DS1488/
MC1488, is a quad line drivers designed to interface data
terminal equipment (DTE) with data circuit-terminating
equipment (DCE). This device translates standard TTL/
CMOS logic levels to levels conforming to EIA-232-D and
CCITT V.28 standards.
The device is fabricated in low threshold CMOS metal gate
technology. The device provides very low power consump-
tion compared to its bipolar equivalents: 500 µA (DS14C88)
versus 25 mA (DS1488).
The DS14C88 simplifies designs by eliminating the need for
external slew rate control capacitors. Slew rate control in ac-
cordance with EIA-232D is provided on-chip, eliminating the
output capacitors.
